To all whom it may concern: 7

Be it known that I, NICOLA CoRsI, a subject of the King ofItaly, residing at Brooklyn, in the city of New York, county'of Kings, and State of New York, have invented certain new and useful Improvements in Automobile Brake- Controlling Apparatus, of which the following is afull,

clear, and exact description, reference being ing a part of this specification.

This invention relates to automobile brake controlling apparatus adapted to automati'cally operate the brake or brakes when the vehicle should strike against an obstacle of some kind; and more particularly relates to means automatically controlling the brake or brakes of an automobile, adapted to be connected to and operated by the resilient brake or brakes of the vehicleon which the same is mounted, and to operate said vbrake or brakes upon said buffer striking against an obstacle. v l 7 Another object istofprovide a novel and improved type of automobile brake controlling apparatus, causing the automatic op-.

eration of the brake or brakes of the vehicle upon said 'vehicle striking against an ob-;

stacle ofsome kind, and 'allowing'the normal operation of the brake or brakes by means of pedal or hand lever, to take place in the ordinary manner.

With theseand other will more fully" appear as the. description proceeds, this invention furthermore consists in certain novel constructions and .ar-

rangements of parts as will be fully described and claimed in theappended claims.

I bumpers is lwell known,.the same absorbing the shock due to sudden impacts through the deformation of their resilient portion, and preventing serious damage to the car or to the obstacle encountered; however, while quite effective when the impact is of moderate proportions, these devices are rather ineffective when the momentum of the car is too great,..and as a consequence the impact is of a violent nature, since the shock absorbing capacity sarily limited. By means of this invention, the efliciency of shock absorbers of the buffer or bumper type may be-considerably increased, by causing the brake or brakes of the vehicle to instantly. co-operate withthe same when deformed through the force of a sudden impact; the momentum of the vehicle being thus partly absorbed by the buffer, and partly by the brake surfaces entering into play as soon as the bufler is deformed.

In this manner the time necessary to bring a'car to a stop will be considerably decreased, and the ability of a shock absorbing device to protect the same against damage, considerably increased. r

and arrangement of the various parts connecting the buffer to the brake or brakes, the braking action may be caused -to take place in of these devices is necesa gradual manner, timed with the gradual increase in the deformation of the bufier occurring before a shock 'is entirely ab. sorbed.
